Supported Applications
The Omega HH74K is a portable, single-channel digital thermometer designed for general temperature measurement using external Type K thermocouples. The series supports applications in greenhouses, office environments, environmental studies, laboratories, workshops, art galleries/museums, weather monitoring, and department stores.
Operating Conditions & Performance
The HH74K measures temperatures from -100 to 850°C (-148 to 1562°F) with a user-selectable Celsius or Fahrenheit display. Accuracy is specified as ±(0.3% rdg + 1°C) on °C ranges and ±(0.3% rdg + 2°F) on °F ranges, stated for ambient temperatures of 18 to 28°C (64 to 82°F). Resolution varies by range: 0.1°C/°F from -59.9 to 199.9 and 1°C/°F at lower (-100 to -60/-80) and higher (200 to 850/1562) extremes.
The device operates in ambient conditions of 0 to 50°C (32 to 122°F) at less than 70% relative humidity. Storage is permitted from -20 to 60°C (-4 to 140°F) with the battery removed, under 0 to 80% R.H. The measurement rate is documented as 2.5 times per second in series specifications.
Configuration Options
The HH74K features a lightweight design with dimensions of 148mm(H) x 48mm(W) x 24mm(D). It includes a magnet hanger for mounting and is powered by three 1.5V AAA batteries, offering approximately 300 hours of battery life under typical use. The unit features an auto power-off function (disableable), max/data hold capabilities, and an adjustable thermocouple offset function.
Key configurable or included elements include:
- Sensor Interface: Accepts standard miniature SMP connectors with flat blades spaced 7.9mm center to center.
- Included Probe: Ships with a free 1 m (40") Type K insulated beaded wire thermocouple, subminiature connector, and wire spool caddy.
- Accessories: Optional soft carrying case (SC74) and optional SA1-K-SC self-adhesive thermocouple are available. Spare thermocouples are listed as Model No. SC-GG-K-30-36.
Key Product Differences
The series is identified by the model number HH74K, designated specifically for Type K (CHROMEGA™-ALOMEGA™) thermocouples. The device includes a NIST-traceable calibration certificate (no points). Safety warnings indicate the instrument should not be used where voltages at the measurement surface exceed 24V AC or DC and is not designed for human applications.
